WAIFLE IRON.

Appuoman ined November 24, 192s. serial no. masc.

Toall 'whom t lmay co'nmf Beit known that 1 Willman/KW.. Donen,. J r., a citizen of the United States,"res'iding a single utensil which can be used as a waille e ironor asa griddle, which costs vpractically no more to manufacture than existing types of waffle irons, which is convenient to use, and attractive in appearance.

I` show the invention as applied to:Y a known type of waffle iron in the accompanying drawings. l

In the drawings: f Fig. 1 is a vertical section on the line 1--1 of Fig. 2; l i 4 I`Fig. 2 is a section on the line 2-2 of tig. 1; v

Fig- 3 is a perspective view of the complete device with the cover in position looking from the rear;

F Fig. 4 is a section on the line 4 4A of ig. l;

5 is a perspective view of the griddle element; and

Fig. 6 is a wiring diagram.

The waie iron consists as usual of two sections 11 and 12 hinged together at 13.

The lower sectlon 11, the heating coils `14,

and the insulation-'15 are enclosed with a cup-shape metal case 16,1provided with legs 17 upon' which the whole device rests.

The upper member 12 of the waiile iron is qleated by electric'resistance coils 18 enclosed in the insulating sheets 19, and lying betweengthe topo'ruback of the element 12 and a griddle member 20, which is provided with a peripheral rim 21, and a downward extending flange 22. The griddle member l20 may be attached to the back of the waiie iron member 12 in any preferred manner,

but Iprefer the one illustrated. This can best be understoodfrom Figs. 1 and 5.

The fiange 22 of the griddle member 20 is formed with `two holes 23 and 24 at approximately diametrically opposite points'. `The aperture v23'is engaged with ak lug 25 cast integrally withthe member 12 ofthe waie iron near the rear thereof. The grid-y dle member isv then swung down into position with its flange surrounding the periphery of the member 12, and is fixed in position by means of-,a threaded stud 26, which passes through the hole 24 and screws in the member 12. The end ofthe retain a nut 27 having a sleeve-like body 28.

The griddle member 20, whennot in use, is concealedby an ornamental cover 29 which has, at its rear, a hole 30 which engages the lug 25, and has at its front a keyhole slot 31 (see Fig. 4). This slot is sodimensioned that the cover 29, after being engaged with the lug25, may be swung down to position, the stud 26 entering the slot 21. The nut 27 is then screwed up and its sleeve-4 like portion 28 enters the circular upper end of the keyhole slot 31 (see Fig.- l), thus` positively locking the cover 29 in place.

The cover 29 is provided witha handle 32 and may, if desired, carry heat insulation, as will be obvious. The air space under the cover- 29 will ordinarily be found tov oer suiicient heat insulation. y

It is desirable; to cut out the lower heating unit 1'4'when the device is being used as a griddle, as much of the heat generated in theunit 14 would be wasted, and as 'stud 26 is vslightly enlarged, as shown, to

there would be the possibility of damage through overheating of the coil. A ny arrangement for cutting out the lower heating units may be adopted but I prefer the one shown. Connection is made to the lower section of the wale iron through suitable ones of three contacts 33, 34, and 35. These are connected up to thecoils 14 and 18 as indicated in diagram in Fig. 6. This permits the coils 14 and 18'to be connected up in series or in parallel to give two different i degrees of heat when these' two coils are heated simultaneously,'and also permits the coil 18 to be heatedalone.

Since the coils 14 and 18 are in dierent sections of the wale iron, the connections between the coils are made by means of a flexible cable 36, which is adjacent the hinfe 13. The presence of this cable requires tie notch 37 to be vformed in the flange 22 of griddle 20 and a similar notch 38 to be formed in the ornamental cover 29.

The griddle member 20, as well as the watlle iron members 1l and 12, is prefern ably composed of alumimnn to obviate the use of grease. The cover members 16 and Q9 can be polished or ornamented in any suitable manner. To use the device as a watlle iron, the cover 29 is left in position and both heating elements' Mv and 18 are used. To use the device as a griddle, the n'ut. 27 is unscrewed and the cover 29 is removed to expose the griddle 20. Under these conditions, the cable lead to the utensil is connected to the terminals 34 and 35, so as to heat only the upper heating coil 18. In this way current is conserved.

The cover 29 may be used in combination with the griddle 2() and heat element 18 to form an oven.

lVhat is claimed is:

1. The combination with a wallie composed of coacting sections, each vided with electrical heating means, of a griddle permanently mounted on the back of one section in close heat-conducting relat-ion with said heating means.

2. A convertible griddle and watile iron element, comprising in combination a inember having one face formed to serve as a griddle and the other face formed to serve as one element of a watlle iron; and electrical heating means mounted Within said member i ron proand arranged to heat both faces simultaneously.

The combination with a wallie iron composed of coactng sections and provided with electrical heating means for each seclion, of a griddle mounted on the back of the upper section in position to be heated by the heating means for that section; and a cover, serving when in place to conceal said griddle, releasably mounted on said upper section.

4. The combination with a waflle iron composed of coact-ing sections each provided with electrical heating means, of a griddle mounted on the back of one section in position to be heated by said heating means; and connections for direct-ing current alternatively at the will of the operator to the heating means of both sections or to the heating means of the griddle-bearing section alone.

5. The combination with a wale iron composed of coa-cting sect-ions, each provided with electrical heating means, of a griddle mounted in the back of the upper section in position to be heated by the heating means of that section; a cover, serving when in place to conceal said griddle, releasably mounted on said 'upper section; and connections for directing current alternatively, at the will of the operator to the heating means of both sections or to the heating means of the griddle bearing section alone.

In testimony whereof I have signed my name to this specification.
